[aspectj-users] Abstract aspect and !cflow(within) results in ExceptionI

[Benjamin Mesing <benjamin.mesing@xxxxxxxxxxxxxxxxxxxxxxxxx>]

Hello,

with the program given below, I get the exception:

Exception in thread "main" java.lang.ExceptionInInitializerError
        at test1.Test.sayHello(Test.java:7)
        at test1.Test.main(Test.java:13)
Caused by: java.lang.NullPointerException
        at test1.Aspect.<clinit>(Aspect.aj:1)
        ... 2 more

Making "Aspect" concrete and removing "ExtendedAspect" makes everything work
fine. 
This appears to be a bug in ajc. Do you agree?

Thanks,

Benjamin
